Description
Technical field
The utility model relates to a kind of combustion gas Forced-circulation Waste-heat Boiler.
Background technology
Waste heat boiler, as the term suggests refer to the boiler utilizing the waste heat in the waste gas in various industrial process, waste material or waste liquid and the combustible burning rear heat produced thereof water to be heated to uniform temperature.There is smoke box, oil burning boiler that flue residue heat is recycled, gas fired-boiler, coal-burning boiler also referred to as waste heat boiler, waste heat boiler can be produced hot water or steam by waste heat recovery and supply other workshop section and use.
But existing waste heat boiler, because the contact surface area crossing water pipe is less, heat absorption is relatively undesirable, and furnace insulation effect is also undesirable.The problems referred to above should be paid attention to and the problem solved in the design and production process of waste heat boiler.
Utility model content
The purpose of this utility model is to provide a kind of combustion gas Forced-circulation Waste-heat Boiler, and to solve in prior art the contact surface area due to tedge existed less, and heat absorption is relatively undesirable, and the furnace insulation effect also problem such as undesirable.
Technical solution of the present utility model is:
A kind of combustion gas Forced-circulation Waste-heat Boiler, comprise body of heater, drum, circulating pump, blast tube, heating surface assembly, down-comer, drum and blast tube are all located in body of heater, drum is located at the sidepiece of blast tube, heating surface assembly is respectively equipped with water inlet pipe and steam (vapor) outlet, steam-water separator is provided with in drum, one end of down-comer is communicated with drum, the other end of down-comer is communicated with heating surface assembly, heating surface assembly is located in blast tube, heating surface assembly is by the entrance of pipeline communication steam-water separator, heating surface assembly comprises pipe group and Left-wing Federation's case, right header, pipe group comprises some water pipes excessively, the two ends crossing water pipe are communicated with Left-wing Federation's case respectively, right header, cross water pipe and adopt horizontal coil, the outer surface crossing water pipe is provided with the honeycomb of some grooves formation, heat-insulation layer is provided with outside body of heater, heat-insulation layer adopts the rock wool layer set gradually from inside to outside, fiberglass cloth, alumina silicate acupuncture blanket layer.
Further, cross water pipe and be also provided with spiral thin steel band.
Further, cross water pipe and be also provided with sawtooth sheet, sawtooth sheet forms helical form.
Further, groove adopts regular hexagon, circle or oval.
The beneficial effects of the utility model are: a kind of combustion gas Forced-circulation Waste-heat Boiler of the utility model, by arranging the honeycomb that some grooves are formed at the outer surface crossing water pipe, the contact area of combustion gas in water pipe and blast tube can be increased, be more conducive to utilize the exchange of waste heat, can effectively improve heat recovery rate.Employing groove is arranged, and not increasing with under the prerequisite of the distance crossing steam in water pipe, can increase heating surface area, further, shortened the contact distance of combustion gas in steam and blast tube in water pipe, the faster waste heat more fully more efficiently absorbing combustion gas, realizes the recovery of heat.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of heating surface assembly in embodiment;
Wherein: 1-body of heater, 2-drum, 3-blast tube, 4-crosses water pipe, 5-Left-wing Federation case, the right header of 6-, 7-down-comer, 8-rock wool layer, 9-fiberglass cloth, 10-alumina silicate acupuncture blanket layer, 11-circulating pump.
Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment one
A kind of combustion gas Forced-circulation Waste-heat Boiler, as Fig. 1, comprise body of heater 1, drum 2, circulating pump 11, blast tube 3, heating surface assembly, down-comer 7, drum 2 and blast tube 3 are all located in body of heater 1, drum 2 is located at the sidepiece of blast tube 3, heating surface assembly is respectively equipped with water inlet pipe and steam (vapor) outlet, steam-water separator is provided with in drum 2, one end of down-comer 7 is communicated with drum 2, the other end of down-comer 7 is communicated with heating surface assembly, heating surface assembly is located in blast tube 3, heating surface assembly is by the entrance of pipeline communication steam-water separator, as Fig. 2, heating surface assembly comprises pipe group and Left-wing Federation's case 5, right header 6, pipe group comprises some water pipes 4 excessively, the two ends crossing water pipe 4 are communicated with Left-wing Federation's case 5 respectively, right header 6, cross water pipe 4 and adopt horizontal line pipe, the outer surface crossing water pipe 4 is provided with the honeycomb of some grooves formation, heat-insulation layer is provided with outside body of heater 1, heat-insulation layer adopts the rock wool layer set gradually from inside to outside, fiberglass cloth 9, alumina silicate acupuncture blanket layer 10.
By arranging the honeycomb that some grooves are formed at the outer surface crossing water pipe 4, water pipe 4 and the contact area of combustion gas in blast tube 3 can be increased, be more conducive to utilize the exchange of waste heat, can effectively improve heat recovery rate.Employing groove is arranged, and not increasing with under the prerequisite of the distance crossing steam in water pipe 4, can increase heating surface area, further, shortened the contact distance of combustion gas in steam and blast tube 3 in water pipe 4, the faster waste heat more fully more efficiently absorbing combustion gas, realizes the recovery of heat.
The rock wool layer, fiberglass cloth 9, the alumina silicate acupuncture blanket layer 10 that set gradually from inside to outside is adopted by heat-insulation layer, the setting of three layers of fire-proof heat-insulating material, the effective insulation to body of heater 1 can be realized, avoid the heat in body of heater 1 too lost, further raising heat recovery rate, and heat-insulation layer all adopts fire proofing material, the security of production can be improved.
